If you’ve seen a photo Zuckerberg from the past few years, you’ve most likely seen him wearing a grey shirt, blue hoodie, jeans, and Nikes.

He has a closet full of grey t-shirts.

Zuckerberg doesn’t just wear any old plain grey Hanes t-shirt, though. His are special ordered from Brunello Cucinelli, and reportedly cost between $300 and $400. A few years ago, H&M rolled out a joke “Zuckerberg collection,” but that’s not on sale anymore.

Klaus Buchroithner, CEO of Vresh Clothing, decided to study Zuckerberg’s shirt closely, and make a replica of it, or as “as close to the original as possible” without being the same exact item — kind of like how Instagram rolls out new features.

Buchroithner looked at the fabric, the color, and even the length of the t-shirt while crafting the replica.
